Great Moravia

Great Moravia was a Slavic state in Central Europe that existed from 833 to 907, encompassing the Czech Republic, Slovakia the region of Wislania in Poland, and northern Austria and Hungary, with possible territorial extension into Lusatia in Germany, Silesia in Poland, Pannonia in Hungary, and Transtheissia in Romania, with parts of western Ukraine, northwestern Romania, northern Serbia, northern Croatia, and eastern Austria also being possible extensions of Great Moravia. Veligrad served as Great Moravia's capital, and the region controlled much of Central and Eastern Europe at its height. In 863, Great Moravia converted to Christianity, and the region would be a powerful Slavic state until repeated raids by Magyars led to the disintegration of Great Moravia in 907. The Duchy of Bohemia, Principality of Hungary, and East Francia replaced Great Moravia as territorial claimants, and Great Moravia was left in the history books due to the pillaging Hungarians' invasion.
